lie it known thati. FRANK B. it'tiiiazia, a

r'ti'lcen of the United States and resident of fqorwalltfin the eounty of Huron and State it @hio. have t: improvements in Earth l Anchors. of llt'ln I hereby declare the following to be hill. -l air, and exact description. such as ll enable others skilled in the art to which appertains to make and-use the same.

The objects of the invention are to provide a simple and etiit-ient form of earth anchor to be used for retaining telegraph and trolley wire supporti ng posts in position and espeoially such posts as sustainthe greatest: strain such as those .used'to support the wires upon curves or angles. The devires are also adaptable for many other uses for whieh earth anchors are or may he em ployed.

The invention oomprises blades'pivoted together to adapt them to told on each other to redure the spread thereof so that they can be readily inserted into a post, hole.

and the blades are so curved at their outer ends that by in ans of pressureupon the blades near their pivotal point they (an be spread transversely apart to ,enter the ground on each side of the hole. The at? ('hor is also provided with a stem or draw bar whirh engages thivblades at points ele-' vated above the pivotal points so that the art of pulling upon. the anehor will prevent the (losing ot' the blades.

The invention further romprises the (ombinaiion and arrangement of the various parts and ronstrurtion of details hereinater more iullv described, shown in the no rompanying drawings and speritirally pointed out in the olaims.

in the arrompa'uving drawings Figure l is an end elevation of the de ireshowing the blades folded for insertion in a post hole: Fig. 52 i8 a side elevation thereof, and Fig. 3 is an end elevation showing the blades expanding as when in use as an anrhor, and the draw bar in position for use.

in these views are the blades pivoted together at I). integrally connected with these blades are the wingplates t. (l provided with guide openings 1). I) in \Ylllt'll slides theT shaped head l) of thedruw bar i in the position shown in Fig. "1- the blades are f lded together to reduru the size asniurh as possibleaml their curved oxtremities A, A turn outward,- so that invented certain new and .use-

when spread apart the will enter the sides of the opening. When in this position taniping tool G is employed to press the der. H. H to force the blades outward until they are expanded to the position shown in Fig. 3. in enlarged upper end F- for the draw hat assists the use ot the tainping tool. (than in this position the draw bar is raised and the 'l headv engages the transverse poi:-

tension l pids the wings together anti prevents the hlades from iiildiiig again. in

no amount of strain ran-open the blades.

This devire is simple and asy of appliration and incapable of getting out of order. The artion of theblades alone when expanding will be suthrient to penetrate the soil it soft but when hard the soil at the hottom of the hole (an be exr-avated to permit the blades to expand and the opening ran then he filled with thoroughly tamped soil. The wings are set at an angle to said blades so that when the blades are closed the wings diverge and when the blades open the wings cometogether and are retained by the pull upon the draw bar. .r.

l-laving desrribed the invention What I claim as new and desire to serure by Let-- ters Patent is: p

1. in an earth an-bhor. in combination. a pair of blades pivoted together and having outwardly rurved extremities. integral wings extending at an angle to said blades draw bar provided with a head traveling in outer edges of said wings.

2. in an earth anrhor. in, romhination. a pair of blades pivoted together and having outwardl vt. turned extremities. said blades provided with wing members angnlarly disposed on (:lt'll side of the pivotal points. said wing 'memln-rs provided with slotted openings and a T headed draw bar adapted I to engage the upper edges of said blades to separate the same. and also adapted to en gage the upper ends of said slots when strain is put on the draw har. p

t. in an'earth anrhor in combination blades pivoted together and having ontwardly rurved rxtrmnitirs. members secured 0 said blades and extending at qual angles l therefrom. and a draw bar slidingly IHOV- able in said members, said drawbar engaghead of the'draw bar down upon the shonltions l. l of the wings and when ptit under this position a rigid anrhor is providedand and provided with guide openings and a,

BEST AVAILABLE COPY said openings. and adapted to engage the BEST AVAILABLE CO ing said blades when forced downward to open the samgend engaging said members when raised to retain said blades in the open position. o 1 In an earth anchor, in combination, blades pivoted together and having outweirdly curved extremities, members operative1y connected with said blades adjacent to the iw otal points thereof, and a draw 10 bar having an extended head, adapted to enand to engage said members to draw upon thesame when the draw bar 1s hfted.

In testimony whereof, I hereunto set my hand this 20th day of April 1912. i
